Bert instead of trying to attack me

why dont you engauge in helpfull posting to why this spur thing is happening.....as you are an engineer
isnt this what oople is for?
and you never answered the question to why your mates car chewed spurs
(trying to get back on track)
if you read my posts again you will see that none of the things i have said are...personal/attacking/or suggesting that i know better than anyone else
just trying to be helpfull and get to the bottom of this problem
i expect a response
cheers
